Title:
Aerosol Fire Extinguisher with Trigger Sprayer
Kind Code:
A1


Abstract:
An Aerosol Fire Extinguisher with Trigger Sprayer that can be easily held in one hand. The extinguishing agent is under pressure in an aerosol can and can only be released by pulling the tab of the trigger sprayer. The Trigger Sprayer Unit cannot be sprayed until the tab is pulled. The Can is a cylindrical canister housing and has a Dip Tube that goes to the bottom of the can to the Fire Extinguishing Agent. There is Propellant in the can that pushes the Fire Extinguishing Agent up through the Dip Tube. Pulling the tab of the Sprayer Unit allows the Trigger to be pressed and be moved so the Trigger Pivoting Member of the Trigger Sprayer Unit is able to press down on the stem of the Mounting Cup of the Can which then allows the Propellant in the Can to force the Fire Extinguishing Agent through the Dip Tube up through the Chamber Hole into the Direction Chamber with pressure out the Nozzle toward the fire. The user then holds down the trigger and sprays the fire with the Fire Extinguishing Agent until the fire is out.

BACKGROUND

Traditional way of fighting fires is the use of a large Fire Extinguisher that can be bulky and has a complicated pull pin mechanism to dispense the fire extinguishing agent. This invention addresses a new way fighting fires using an aerosol can and trigger sprayer that is both easy to use and fast. The Trigger Sprayer allows the user to be able to pull the tab and spray a fire extinguishing agent onto the fire to put the fire out. When the tab is not pulled the Aerosol Fire Extinguisher with Trigger sprayer cannot be sprayed. Additionally this invention can easily be held in one hand for ease of use and portability.

SUMMARY OF THE INVENTION

The invention is an aerosol fire extinguisher with a trigger sprayer. In a preferred embodiment of the invention the trigger sprayer is fitted onto a mounting cup with a dip tube going to the bottom of the aerosol can to the Fire Extinguishing Agent. The Direction Chamber allows the Fire Extinguishing Agent to flow through the trigger sprayer to the nozzle where it will flow out toward the fire. The Trigger pivots up and down that puts pressure on the Direction Chamber that puts pressure on the actuator stem allowing the fire extinguishing Agent to flow up. The nozzle on the trigger sprayer can is configured to allow the fire extinguishing agent to flow out rapidly. There is a propellant inside the can with the Fire Extinguishing Agent. A Mounting Cup is placed in the Hole ate the top of the Aerosol Can and holds the pressure of the Propellant and Fire Extinguishing Agent. The Mounting Cup of the aerosol can has a actuator stem that when it is depressed cause the fire Extinguishing Agent to flow out. The propellant can be CO2, Air, Nitrogen or 134a. The aerosol can is cylindrical. The Trigger sprayer of the aerosol fire extinguisher has a tab on top of it that can be easily be pulled off which allows the trigger to be depressed and ready to be used. When this tab is not pulled no Fire Extinguishing agent can come out of the aerosol fire extinguisher for easy storage. The Tab has breakaway hinges and can be snapped off easily. The Trigger can be depressed by an index finger or other fingers to release the Fire Extinguishing Agent. The Trigger Sprayer has a nozzle wherein the Fire Extinguishing Agent can flow out.

OPERATION OF THE INVENTION

When the Tab is not pulled the Trigger of the Aerosol Fire Extinguisher is locked and cannot be sprayed. The operation of the Aerosol Fire Extinguisher with trigger sprayer is when there is a fire and it is needed for use, the user simply pulls the tab of the Aerosol Fire Extinguisher Trigger Sprayer which is located on top and this enables the trigger assembly to be pushed down on the mounting cup that has a stem sticking up that when depressed allows the propellant in the can to push the Fire Extinguishing Agent up through the stem through the Trigger Sprayer Unit through the Direction Chamber then through the Nozzle toward the fire. The Fires Extinguishing Agent comes out with pressure and because the trigger has a nozzle the user can easily identify the direction to spray the Fire Extinguishing Agent.

A Trigger 15 fits inside the Trigger Sprayer Unit 8. The Chamber Hole 11 goes into a Direction Chamber 12 which is hollow and allows the Fire Extinguishing Agent 7 to flow through. The Fire Extinguishing Agent 7 flows through the Chamber Hole 11 into Direction Chamber 12 out a Nozzle 14. The Trigger 15 Pivots up and down by being pressed and by way of its trigger Pivoting Member 16. The Trigger 15 has a Nozzle Holder 25 that holds onto the Nozzle 14.

Referring now to FIG. 5000 which shows a perspective side view of a Aerosol Fire Extinguisher with Trigger. A Aerosol Fire Extinguisher with Trigger Whole Unit 18 is shown as the whole invention. In this perspective view the Can 1 is shown filled with the Fire Extinguishing Agent. The upper portion of the can is filled with the Propellant 6 and the Dip Tube 5 goes down to the Fire Extinguishing Agent 7. A Mounting Cup 3 holds the pressure inside the Can 1. The Trigger Sprayer Unit 8 fits onto the Actuator Stem 4 onto the Mounting Cup 3. The Direction Chamber as it fits on the Actuator Stem 4 is shown. The Tab 17 as it fits on top of the Trigger Sprayer Unit 8 and the Nozzle 14 wherein the Fire Extinguishing Agent 7 flows out. The Trigger Pivoting 16 can be seen in

Referring now to FIG. 6000 shows a view of the trigger sprayer looking from above. The Tab 17 is shown as it sits on top of the Trigger Sprayer Unit 8.
